Reciprocating in-floor pool cleaner head

A device for use in a swimming pool structure, the swimming pool structure including a pool and a circulation system having a piping assembly and a pump for cyclically communicating water through the piping assembly between the pool and the pump, and the piping assembly terminating in a collar installed the swimming pool structure, the device comprising:

• an insert having an inlet and configured to be applied to the collar;
• a piston formed with a nozzle, the piston carried in the insert for reciprocal movement between a lowered position and a raised position into a first indexed orientation of the nozzle above the insert;
• the nozzle rotates to a second indexed orientation, adjacent to the first indexed orientation, in response to the piston moving from the raised position to the lowered position to the raised position in response to the cyclical application, removal, and application, respectively, of water through the inlet;
• upper and lower engagement assemblies prevent rotational movement of the nozzle with respect to the insert in the raised and lowered positions, respectively, of the piston;
• and
• a weight biases the piston into the lowered position.

A device for use in a swimming pool structure, the swimming pool structure including a pool and a circulation system having a piping assembly and a pump for cyclically communicating water through the piping assembly between the pool and the pump, and the piping assembly terminating in a collar installed in the swimming pool structure, the device comprising:

• an insert and an end cap cooperating to define a chamber coupled in fluid communication to the piping assembly through an inlet in the end cap;
• a piston including a weight and a nozzle, the piston carried within the chamber for reciprocal movement between a lowered position, into which the weight biases the piston, and a raised position, in which the piston is in one of a plurality of indexed orientations and the nozzle is free of obstruction above the insert;
• the piston rotates to an adjacent indexed orientation in response to reciprocation of the piston between the raised and lowered positions in response to the cyclical application of water flow through the chamber from the inlet to the nozzle;
• spaced-apart upper and lower engagement assemblies prevent relative rotational movement of the piston and the insert in the raised and lowered positions, respectively, of the piston;
• and
• a minor outlet formed between the insert and the piston is in fluid communication with the inlet to allow water to flow from the inlet, between the insert and the piston, and out the minor outlet.
